This study sought to explore the enhancement of the introduction of teaching and learning methods for Problem Based Learning (PBL) and the evaluation factors to evaluate them effectively through an understanding lecture in Cultural Content Planning. It was intended to incorporate a practical zero-volume education methodology of problem-oriented learning and sufficient leading learning to reflect storytelling in the entire process of completing a cultural content with culture, cultural content, and content planning. To this end, the role of teaching methods should be faithful to ensure that teamwork and cooperation can be done organically according to the educational field, practice and situation. Students who take classes were asked to meet demand, reflect it through surveys, apply real-world problems, and acquire the entire course. Learners had to cooperate with each other until planning cultural content and completing the results through classes, and they evaluated themselves and colleagues in teamwork until the last result was completed from creative ideas. The results were shared together and the students were able to investigate the necessary PBL evaluation factors for themselves, and the prior research and survey on the method of PBL evaluation was conducted to derive the factors of understanding of cultural content planning. The derived assessment elements were able to identify priorities between the assessment elements using basic statistics, word cloud analysis, and AHP analysis. The components of the assessment derived were communication skills, basic knowledge, reasoning process, expertise, and evaluation techniques. Through this article, I was able to lead the understanding of cultural content planning to problem-oriented learning classes and encourage students to be familiar and smooth.

Digital image provides many conveniences at the internet environment recently. A great number of applications, like Digital Library, Stock Image, Personal Image and Important Information, require the use of digital image. However it has fatal defect which is easy to be modified because digital image is only electronic file. Numerous digital image forgeries have become a serious problem due to the sophistication and accessibility of image editing software. Copy-Move forgery is the simplest type of forgery that involves copying portion of an image and paste it on different location within the image. There are many approaches to detect Copy-Move forgery, but all of them have their own limitations. In this paper, visual and invisible feature based forgery detection techniques are tested and analyzed. The analysis shows that pros and cons of these two techniques compensate each other. Therefore, a hybrid of visual based and invisible feature based forgery detection that combine the merits of both techniques is proposed. The experimental results show that the proposed algorithm has enhanced performance compared to individual techniques. Moreover, it provides more information about the forgery, like identifying copy and duplicate regions.

Mammary gland tumors are the most common neoplasms occurring in female dogs. The treatments of mammary gland tumors are surgery, chemotherapy, hormonal therapy and radiational therapy, but surgical removal remains widely accepted treatment option for mammary gland tumors. The purpose of this study is to evaluate clinical outcomes of dogs which are performed surgical excision. Medical records were reviewed for dogs(79 cases) with mammary gland tumors treated surgically at Veterinary Medical Teaching Hospital in Seoul National University from 2001 to 2005. While 49 cases(62.0%) were benign, 30 cases(38.0%) were malignant tumors. The mean age of these dogs was 10.4 years old(range $1{\sim}16$ years). The maximal diameter of malignant tumors were various, whereas most of the benign tumors were smaller than 3cm(36 cases, 73.5%). In 12 cases(15.2%), regional lymph nodes were enlarged and lymph nodes of 3 cases had resected surgically. The performed techniques were total mastectomy, regional mastectomy, simple mastectomy, lumpectomy and unilateral mastectomy in order. Twenty-eight cases(35.4%) had postoperative complications consisted of recurrence of tumors, necrosis, dehiscence, delayed healing and edema of limbs. The recurrence rates of benign and malignant mammary gland tumors were 8 cases(16.3%) and 6 cases(20.0%). Metastasis rate was 7 cases(8.9%). Although postoperative complications were no remarkable difference in recurrence rates among surgical techniques in this study, other complications such as edema of limbs, necrosis, dehiscence and delayed healing were remarkable difference as surgical techniques. Therefore, this result suggest that choice of appropriate surgical techniques should be determined according to each patient's physical status and characteristics of tumors.

The purpose of this research is to propose a plan on migration policy based on features, through analyzing the migration adaption process and the farming life of the back-to-countryside population throughout the nation. For this, survey has been conducted to find out urban-to-rural migrants' motives and characteristics. The major reason for the migration was the household's financial condition, and the most of migration decisions were made by either one's spouse or parents. The migration fund was primarily spent in early agricultural activities and it was the neighbors who aided them the most whilst teaching them many farming techniques. Some government-supported policies are being highly demanded regarding the lower level of income (than urban life) and difficulties of raising cultivation funds; these two things are what migrants consider as the most inconvenient and suffering matters in farming life. Many surveyee have responded that they would constantly stay in the rural area and continue on their life as a farmer, giving a promising prospect for future farmland life. Based on these trends and features, development strategy regarding elaborate settlement plan of urban-to-rural migration is necessary.

The uniqueness of Bali is inseparable from its culture and religion. Embedded in the cultural environment, textiles become one of the most important aspects in Balinese life as it is used as a medium in sacred ceremonies. Balinese textiles are made and used under special conditions according to Hindu teaching. This paper aims to observe the aesthetics of Balinese sacred cloths that are seen in their techniques, colors, and patterns. Quantitative research included in this study is based on 261 images taken from literature review and Museums. Field research was done in eastern part of Bali. This paper has divided the era between ancient and modern times. The ancient era before the 20th century used textiles for religious purposes. Modern era started from the colonialization period by the Dutch in Bali during 1910-1942 added economic values to the textiles. The independence of Indonesia in 1945 created Balinese textiles as a unifying value as one of the identity of Indonesia. The techniques are classified as Weft Ikat, Double Ikat, weave with Supplementary Weft, and Prada. The colors of the ancient era are 'fixed' with the restriction of the colors red, black, and white. The colors of modern era are 'festive' with combination of yellow, green, blue, and purple. The characteristics of patterns are geometric, natural, human, and animal groups. Field research in this paper observes Klungkung Village that produces Endek and Songket cloths. The aesthetics of Endek cloth is 'royal statement' and Songket cloth is a 'cultural heritage.' Nusa Penida Island produces Cepuk cloths and is a 'protective guardian.' Satria sub-district produces Prada cloths and appears to be an 'opulence charm.' Lastly, Tenganan Village produces Geringsing cloth which possesses a 'legendary legacy.' To sum up, Balinese sacred cloth essence is a balance of tradition and modern.

The purpose of this study is to review empirical research on Form-focused instruction (FFI) in Korean language education from a critical perspective to better understand the effectiveness of FFI. To achieve this goal, several databases were searched to locate relevant experimental and quasi experimental studies published in peer-reviewed journals. Out of 66 studies collected, 12 studies met the inclusion criteria. The studies were then analyzed in terms of subjects, target grammar, treatment, measurement, and the learning outcomes of different techniques. In general, several types of FFI techniques had positive effects on helping learners acquire Korean as a second or foreign language. The results of the study will provide a conceptual framework which identifies the major factors affecting the effectiveness of FFI. The results will also be able to inform future meta-analytical research of existing studies.

This study was conducted to investigate and improve experiences regarding breastfeeding education. Questionnaires were distributed to 185 women with children 24 months of age and younger. The period of breastfeeding was about 7.2 months and showed significant differences (p<0.01) according to women's age. About 56% of the respondents participated in breastfeeding education. Women with 3 or more children showed the highest rates of participation compared to the women in other groups(p<0.05). The reason for nonparticipation showed significant differences (p<0.05) according to women's occupation. The biggest reason for nonparticipation was 'lack of time' for housewives and 'no information' for working women. The subjects of education were benefits(20%) and techniques(19%) of breastfeeding, breast care before and after delivery(15%), nutrition care for breastfeeding mothers(11%), etc. The teaching method used most frequently was lecturing(32%). Around 81% of women were not satisfied with their breastfeeding education. The most useful subject was breastfeeding techniques(59%). Thirty percent of women pointed out that 'assessing mother's milk quantity' was the subject which women wanted to learn but were not taught enough about. Around 76% of women wanted more education and preferred personalized education such as home visitation(35%) and personal counselling(27%). Desired education methods showed significant differences(p<0.05) according to women's occupations. 'Home visitation' was the most preferred method for housewives and 'personal counselling' for working women. These results showed breastfeeding education was not helpful for practical life. Therefore, breastfeeding education should reflect women's individual needs to heighten its effectiveness.

Purpose: The main objective of this study was to develop a continuing education program for school health nurses using the Internet, and evaluate the satisfaction of users. Method: A survey using a self reported questionnaire was done to identify areas where education is needed. A stratified random sampling method was employed to select 1.746 school health nurses and to receive the respondings from 584 school health nurses. The contents of the module for the education program were determined to be counseling and teaching techniques to meet health care needs related to sex, and cessation of smoking. The researchers wrote the educational content for the program, and the storyboards and illustrations appropriate to the module were constructed and the domain was registered. The web site was named 'www.healthyyouth.org'. Results: Three topics were identified where education is needed: youth and sex, youth and smoking, and counseling techniques for children, and programs were developed under the web site named. 'www.healthyyouth.org'. Over 90 percent of the respondents reported that the web site was useful and 100 percent reported that they would recommend the web site to other school health nurses. Conclusion: The web based program allowed school health nurses to study and improve their health care knowledge and skills. Since almost all schools in Korea have personal computers in the infirmary, accessibility to the program is excellent. Based on the results of this study, this type of education program will be a useful method for the continuing education of school health nurses.

Objectives: The unilateral cleft lip (UCL) repair technique has evolved extensively over the past century into its modern form and has been identified as an important determinant of treatment outcome. The aim of this study was to evaluate and compare treatment outcomes following repair of UCL using either the Tennison-Randall (triangular) technique or the Millard rotation-advancement technique. Materials and Methods: This was a prospective randomized controlled study conducted at the Lagos University Teaching Hospital between January 2013 and July 2014. A total of 48 subjects with UCL presenting for primary surgery and who satisfied the inclusion criteria were recruited for the study. The subjects were randomly allocated into two surgical groups through balloting. Group A underwent cleft repair with the Tennison-Randall technique, while group B underwent cleft repair with the Millard rotation-advancement technique. Surgical outcome was assessed quantitatively according to anthropometric measurements, using a method described by Cutting and Dayan (2003). Results: Our 48 enrolled subjects were evenly divided into the two surgery groups (n=24 for both group A and group B). Twenty-seven subjects were male (56.3%) and 21 were female (43.8%), making a sex ratio of 1.3:1. The Millard group showed a greater increase in postoperative horizontal length and vertical lip height and a greater reduction in nasal width and total nasal width. Meanwhile, the Tennison-Randall group showed better reduction of Cupid's-bow width and better philtral height. Conclusion: We did not find any significant differences in the surgical outcomes from the two techniques. The expertise of the surgeon and individual patient preferences are the main factors to consider when selecting the technique for unilateral cleft repair.
